BUTTER on THE LIKE Patented ct.26,1l91l5.

Application filed Apri114, 1914. Serial No. 831,871.

To (ZZZ whom it may camera:

Be it known that I, FERDINAND VON EULENFELD, a subject of the German Emperor, residing at Wilson street, Finsbury, London, England, have invented new and useful Improvements in Machines for Cutting or Slicing Bread and Spreading Butter or the like Thereon, of which the following is a specification.

This invention relates to machines for cutting bread into slices and at the same time spreading butter or other substance upon the cut surface, and to that class of machine described in the specification of my former British Patent No. 16729 of 1908, comprising a pivoted operating handle, a knife or cutter mounted thereon so as to cut with a reciprocating and shearing action when the handle is oscillated, a butter container from which the butter is forced by means of a piston which is actuated by the handle throughthe medium of a screw and ratchet feed, and means for varying the quantity of butter ejected and spread on the bread.

The objects of the present invention are to simplify the construction and Working of this class of machine, and to'provide new and improved means for feeding and spreading the butter or the like, whereby the quantity ejected can be regulated, and the machine adjusted to spread slices of bread cut from loaves of varying depths.

To enable my invention to be fully understood I will describe it by reference to the accompanying drawing, in which Figure 1 is a sectional sideelevation of a machine of the kind described having the improvements applied thereto. Fig. 2 is a section on the line 2-2, Fig. 1. Fig. 3 is a sectional plan view. Fig. 4 is a. sectional eleration, the section being partly on the line Fig. l, but drawn to a larger scale. Fig. 5 is a view at right angles to Fig. l, but showing" only a part of the mechanism.

Fig. 6 is a plan of the parts shown in Fig.

5. Fig. 7 is a similar view to Fig. 6, but showing the parts in a different position. Fig. 8 is a view of a detail of the mechanism illustrated in Figs. f to 7 and Figs. 9, 10 and 11 are detail views of the spreader and parts cooperating therewith a is the frame of the machine and b is the table upon which the bread to be sliced is placed.

c is the pivoted handle and cl is the knife or cutter which is mounted thereon so as to be reciprocated as the handle is oscillated vertically up and down, the reciprocation of the said knife being effected in the known manner by the teeth al on its upper edge which gear with the pinion (2 also in mesh with the toothed segment d upon the frame a of the machine.

6 is the cylindrical butter container and f is the piston which is designed to be moved therein as the handle 0 is reciprocated for the purpose of ejecting the butter into the latter, as will hereafter be more particularly described.

The pivotal mounting of the handle 0 comprises a tubular shank 0 provided upon said handle and freely mounted in a bearing a" inthe frame a.

In the improved machine the butter is forced from the. butter container 6, preferably in the manner hereinafter described to a spreading device which is carried by the handle 0 and which comprises an inner cylindrical member 9 in connection with the discharge passage 9 from the butter container e and formed with the longitudinal orifice g? in its underside, and an outer member h of larger diameter and surroundingthe said inner member 9. This outer member h also has a longitudinal orifice hwhich is, however, formed in it in a position displaced relatively to that in the inner member. Rotatably mounted on the outer member kis the sleeve 6, also provided with a longitudinal orifice 2' which, at certain positions of the sleeve, is designed to register with the orifice 71, in the outer member h. On the sleeve i adjacent to its orifice i there is arranged a pair of spreading lips j, between which is forced the butter supplied from the container by the inner member 9 of the device and which has become evenly distributed by its passage in the annular space between the two members 9 and it. These lips j, j serve to spread the butter over the bread on the down stroke of the handle and, in the spreader illustrated, the upper lip j is formed of strips of leather while the lower lip is constituted by the termination of the orifice i To partially turn the'sleeve i upon the outerv member h at the proper time so as to bring the'longitudinal slot's'z' and h into tively to the slot 9 .a peripheral notch m m and disk Z are rotated inthe direction of the register and, at the same time, to tilt the spreading lips j, y' into contact with the cut surface of the bread, I provide projecting arms 70, is upon the sleeve 2' and a cam device comprising a disk Z which is connected to the pinion (Z which drives the knife so that it rotates with the said pinion, the said disk having a peripheral tooth or projection Z Behind the disk Z there is loosely mounted upon the boss Z a ring or washer m, Fig. 8, which is arranged with one face in contact-with the adjacent face of the said disk. This washer or ring is provided with and a tooth or proection m which projects beyond the rear face of the said ring as shown in Figs. 6 and 7 and is caused to bear normally against the tooth Z on the disk Z by the coil spring n. In its normal relative position to the disk Z and notched ring, the notch m in the latter is covered by the tooth Z on the disk, as shown clearly in Figs; 5 and 6. The arm 76 on the sleeve 2' is normally caused to bear against the rear face of the washer m by means of the spring 0, one end of which is connected to the arm 0 on the said sleeve and the other to a point 0 on the handle 0. To enable the machine to be adapted to spread butter on loaves of difierent sizes I provide a bar 7' which is arranged to slide in guides adjacent to the lower lip 7' of the spreader, the said bar cutting off more or less of the butter orifice according to its position This device is shown in Figs. 4 and 9.. In conjunction with this device I fit within the inner cylindrical member 9 a valve in the form of a tube 9 Figs. &, 10 and 11 which has a ll-shaped peripheral slot g. This valve g can be turned by means of the external handle 9 so as to vary the position of the ll-shaped slot 9 relain the member ,1 and thus regulate the butter discharge.

With this arrangement when the knife (Z is making the downward movement, the ring by the pinion (Z arrow, Fig. 7, so that the rearward projection m of the tooth m on the said ring m comes into contact with the arm and arrests further rotation of the ring, the disk Z continuing its rotation so that the tooth Z separates from the tooth m and allows the arm is to move between them underthe influence of the spring 0 and to turn the sleeve 2' so asto tilt the spreader j, j to the bread being cut. The continued downward or cutting movement of the handle o rotates the disk Z'so as to wind up the spring n. Immediately before the knife cZ, however, arrives at the end of its cutting movement the other arm 70 on the sleeve 71 makes contact with a stop 72 on the frame a so as to rock the sleeve 2' away from the surface of the bread and withdraw the arm 70 from engagement with the disk Z and notched ring m, which latter then instantly returns to its normal position under the action of the spring a; the arm 72 on the return or upward movement of the handle 0 rides over the rearward projection m of the ring m, which projection is made with an inclined or cam-shaped surface for the purpose, so that the spreader is maintuined out of contact with the bread during such return movement. The tooth Z on the disk Z is formed with a rearward projection Z so as to prevent the arm I! from passing into the notch m during the return movement of the handle. The position of the parts shown inFig. 6 corresponds with that shown in Fig. l in which figure the handle is moving upward.

In the event of the knife not reaching the limit of its cutting movement and withdrawing the arm is on the sleeve 6 froln the disk Z and notched ring m, it will be seen that the said arm 70 will form an obstruction to the rotation of the disk and the return 10"611161113 of the knife, so that such movement cannot be effected unless the knife completes the cutting movement. In order that the cam-disk Z may be adjusted in position so as to adapt the device for cutting and spreading bread of different depths, the inner face of the boss Z of the said disk is formed with serrations or teeth 9 which are designed to be clamped against correspond ing serrations or teeth 1' upon the opposite face of a shoulder s on the stem of the pinion d*. The parts are clamped together in the desired position by means of the wingnut t which screws on to the projecting end of a bolt 6 u is a spring catch which is provided upon the sleeve 2' and designed to engage with a pin a on the tube It whereby it can be held out of its operating position, if required.

The cylindrical butter container 0 is detachably connected to the feed ratchet wheel 0 by means of the stirrup e and e is a pawl mounted on the frame of the machine so that by the oscillations of the handle 0, the container 6 and the piston f, which is on a spindle f in the container, are given an intermittent movement of rotation in one direction whereby the piston f, the rod f of which is screw-threaded and engages in the screw threaded tube f carried by the handle 0, is fed forward on the downward or operative stroke of the said handle, during which the container is held against rotation by the said pawl. e is a second pawl which is adjustably mounted in a slotted lever pivoted at e to the frame a: and the tail of which is held by the spring 6 against the cam e keyed to the elbow of the handle (1. As will be understood with this construction when the handle is moving downward the camr moves the lever 6 and so causes the pawl c to move forward the ratchet wheel 0 a distance which depends upon the adjustment of the said 'pawl in the slotted lever 6 The piston f 's made hollow and the butter forced from the container is caused to pass through the said hollow piston and into the tubular member 9 on its way to the spreading device.

4) is a mixing device which is located in the butter passage between the butter container e and the spreading device for the purpose of rendering the consistency of, the butter more homogeneous. This device consists of a plate which is rotatably mounted in the elbow of the handle 0 through which it projects into the hollow piston rod f This plate is provided with alternating teeth or notches on its two opposite edges, the teeth on one edge being opposite the notches on the other. The shank of the said device projects through the elbow and this projection is designed. to receive a key or the equivalent by means of which it can be turned so that the butter may be mixed or disturbed, should this be necessary at any time.

10 is a loose bread support which is placed upon the table 6. The latter is made with slots 6 with which'engage pins w upon the underside of the support w. 10 is a cam piece projecting from the side of the sup port to intothe path; of the projecting head 6! of the bolt 6 lVith this arrangement the bread to be cut is placed upon the support to which is then pushed as far as possible toward the knife during the cutting operation. The contact of the aforesaid head CZ with the cam piece Q02 at the termination of the cutting movement pushes back the support to thus removing the bread out of contact with the knife during the succeeding upward motion of the latter. The extent to which the loaf can be pushed forward toward the knife before the cutting operation, is regulated by the adjustable stop e0 which is carried by the knife.

0c is a perforated box detachably secured to the handle 0 just below the elbow portion of the latter, the said box containing a lump of charcoal and having suspended from it the spirit lamp y. The lamp can be used for heating the charcoal which warms the butter in the elbow should the butter become too hard by reason of low temperatures.

In practice a set or series of butter container-s of difierent capacities may be provided, any one of which may be applied to the machine as required.
